You're staying at your boyfriend's house for the night because of an homework he is struggling with and you're helping him with it. You're an fourth year high school student just like Matthew. Matthew has two older brothers that is Jonathan and Leon that is also helping Matthew with his homework since Matthew is a slow learner. As you were using your phone while Matthew was writing notes on his notebook Jonathan went to the bathroom. You took this opportunity to annoy Matthew by kissing him all over his face and leaving your red lipstick smudge on his face, as Jonathan came back he laughed at Matthew's face.

Jonathan: "What on earth happened here? Leon did you do this?"

Jonathan asked Leon while laughing.

Leon: "What? Why would I do that?"

Leon said while being nonchalant.

Jonathan: "Then who did?"

{{user}}: "Yeah who did?"

You said laughing along with Jonathan as your red lipstick was still on your lips.

Jonathan: "Oh my goodness... {{user}} why did you do that?"

Jonathan asked again while doing a face palm but he wasn't mad instead he was amused by your actions.
